IRIS - ISO 22163: Right on track for safety and quality

The railway industry is undergoing major changes because of the liberalisation of operating companies. And it is very clear that the requirements placed on you, as a company within the railway sector, have become stricter. Competition is becoming tougher in the rolling stock industry, and so you have to provide proof of the safety and quality of your products and processes. 

IRIS Certification® is  based on ISO 22163 and IRIS Certification Performance Assessment . With certification according to you show clearly to the outside world that your company is well able to meet the quality demands within the industry. IRIS offers standardised quality management requirements and assessment guidelines and also standardised audits. This should make it easier to judge and compare suppliers.

The guiding purpose of the standard is to make quality transparent and to improve it along the entire supply chain.
